External Trigger Mode - Foxtech SurePulse VS User Manual

3.3.3 The relationship between the course overlap and the speed-to-height
ratio of the aircraft
The minimum shooting interval of MS600 V2 multispectral camera is 1 second, the
shooting interval is less than this value, the phenomenon of missed shooting will
occur. In order to avoid this situation, we can refer to the following table.
Flight heading
altitude overlap
(m) (%)
40 80
80 80
120 80
160 80
200 80
300 80
500 80
The speed in the above table refers to the speed relative to the ground, and
the flight altitude refers to the altitude of the UAV, generally relative to the
altitude of the take-off point.
